Abstract
Filters and methods which may be used with millimeter-wave and terahertz frequency range are disclosed. The filter is formed as an electrical prism which may include a first lattice forming an interface with a second lattice. Each lattice may include a plurality of passive elements, such as inductors, capacitors, and the like. The first lattice may include an input disposed at an input boundary thereof, while the second lattice may include an output disposed at an output boundary thereof. Furthermore, the first and second lattices may be configured to receive a signal at the input of the first lattice, propagate the signal to the interface, and direct the signal to the outputs of the second lattice.
